An internship in Tokyo is more than an international work experience. It is a deep dive into a professional culture where respect, precision and teamwork matter every day.
Former Abroad Internships interns often describe Tokyo as professional, safe, intense and incredibly rewarding. But the biggest success factor is not only your technical skill. It is how well you understand and adapt to Japanese work culture.
Here is what you should know before starting your internship in Tokyo.
First impressions: punctuality and formal dress
In Tokyo, arriving “on time” usually means arriving early.
A good rule: be there at least 5 minutes before your agreed start time. It shows reliability and respect for other people’s schedules.
Dress also matters. Many Japanese offices are more formal than workplaces in the Netherlands, Belgium or other Western countries. When in doubt, choose slightly more formal clothing.
Do’s
- Arrive 5 to 10 minutes early.
- Dress neatly and professionally.
- Greet colleagues calmly and politely.
- Keep your phone silent during meetings.
Don’ts
- Arrive late without notifying anyone.
- Dress too casually on your first day.
- Act overly informal with senior colleagues.
Workplace hierarchy: how to communicate with seniors
Japanese companies often have a clear sense of hierarchy. Age, role and experience can influence how people communicate and make decisions.
This does not mean you should stay silent. It means timing and tone matter. Speak respectfully, listen carefully and observe how communication flows within the team.
A useful tip from former interns: watch how colleagues interact before jumping in. Who speaks first? Who summarizes? Who makes the final decision? These small cues help you understand the workplace dynamic.
Useful phrases:
“Would it be okay if I share an idea?”
or
“Would you like me to prepare a suggestion for this?”
Meeting culture and the role of silence
In many Western workplaces, silence can feel awkward. In Japan, silence can signal thoughtfulness, respect or careful decision-making.
During meetings, you may not be expected to give your opinion immediately. Sometimes input is requested only after senior colleagues have spoken.
What works well:
- Take notes.
- Show that you are listening.
- Wait until you are invited to contribute.
- Share ideas calmly and clearly.
- Avoid interrupting others.
After work: nomikai and how to say no
A nomikai is an after-work drink or dinner with colleagues. It can be a valuable way to connect with your team outside the office.
Still, you do not have to say yes to everything. If you are tired, have another commitment or do not drink alcohol, you can politely decline.
Polite ways to say no:
“Thank you so much for inviting me. I really appreciate it, but I have another commitment tonight.”
Or:
“I’d love to join next time, but tonight I need to rest.”
If you do not drink alcohol, simply choose water, tea or a soft drink.
Common mistakes Western interns make
Most mistakes happen because of cultural differences, not bad intentions.
Mistake 1: being too direct
Dutch-style directness can sometimes feel harsh in Japan. Phrase feedback more softly and respectfully.
Mistake 2: trying to influence decisions too quickly
As an intern, you build trust first. Show that you observe, learn and follow through.
Mistake 3: misreading silence
Silence does not automatically mean disagreement. It can be part of careful communication.
Mistake 4: asking for help too late
If you are unsure, ask for clarification early. That is usually better than guessing.
Mistake 5: forgetting the group
Group harmony matters. Think not only “What do I think?” but also “What helps the team?”
Practical: visa, transport and SIM card in Tokyo
Before your internship in Japan, check which visa or residence status applies to your situation. Japan’s Ministry of Foreign Affairs recommends checking visa details through the Japanese embassy or consulate responsible for your country of residence.
If you are already studying in Japan, paid internships or internships above certain working-hour limits may require extra permission. Study in Japan notes that students may need permission for activities outside their residence status, especially for paid work or internships exceeding 28 hours per week.
For transport, an IC card is one of the easiest ways to move around Tokyo. GO TOKYO explains that prepaid rechargeable IC cards can be used on many trains, subways and buses, as well as at participating shops and vending machines. From May 2026, TOURIST PASMO is also being offered again for short-term visitors, with a 28-day validity period and sales around Narita and Haneda airports.
For mobile data, you can usually choose between a local SIM card, eSIM or pocket WiFi. Before departure, check whether your phone is unlocked and supports eSIM.
